ATTACHMENT FOR TRANSMITTERS.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application filed July 20.1904. Serial No. 217,362.

To all whom it may concern:

Be it known that I, SIDNEY A. BEYLAND, a

citizen of the United States,\residin g at El yria,

in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Attachments for Transmitters, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to card-holders and the like in ,which number-cards or other indicia are held; andit has particular reference to such devices as applied to telephone instruments.

It has for its object the production of adevice of this character which shall securely hold the card or other indicating-slip support ed by it, which shall be easy of attachment to the apparatus with which it is to be used, which will not readily slip or become displaced when in position for use, and which will be simple and economical to manufacture, as well of a pleasing appearance.

In order to attain the objects of my invention, I provide a frame, which may conveniently be made of sheet metal stamped up, and upon this frame certain projecting portions, which take under the mouthpiece to be clamped thereby, the same portions engaging certain cooperating parts of the transmitterfront plate to be locked thereby in the act of clamping, so that accidental displacement is impossible. Incidentally my improved holder can be made to fit orifices of somewhat different sizes and is economical to manufacture by reason of an economy in metal.

My invention is illustrated in the accompanying drawings, wherein the same letters of reference point out the same parts throughout.

In the drawings, Figure 1 is a side View of a transmitter-front of standard design with my plate-holder attached thereto. Fig. 2 is a face view of the same with the mouthpiece removed. Figs. 3 and 4 are similar views showing a modified form of holder.- Fig. 5 is a bottom View of another modification. Fig. 6 is a bottom view of the modification shown in Figs. 3 and 4:.

Referring to the drawings, T represents the front plate of a transmitter of standard so-called solid back granular type. This plate is provided upon its front with its central boss upraised'from its surface and bored out or cast with a central orifice, which is screw threaded to receive the mouthpiece T. The mouthpiece is shouldered at t this shoulder coming down upon the flange 6 when the mouthpiece is screwed home. The diaphragm of the transmitter is secured beneath the front plate T, being visible through the central orifice in Figs. 2 and 4. None of the other operating parts are shown, however, as they do not relate to my present invention.

Attached to the transmitter-front T in the manner I shall point out is the card-holder H, and herein as in the method of its attachment my invention resides. The holder H is formed of sheet metal stamped out to form the open frame it h h constituting asight or body portion, upon which downwardly-projecting fingers 7&3 are produced. The side members it have their edges rolled over backwardly, as shown in Figs. 1 and 3. so that a card 0 may he slipped down and held with its edges in the grooves thus 'formed'and its face visible through the sight portion of the frame from the front thereof, as shown in Fig. 4:. In this figure the outline of the card is dotted upon the frame. In order to prevent slipping or accidental displacement of the card, I form a small finger 7L upon the middle portion of the upper edge of the member 71. This finger or edge is turned over the edge of the card after it is in position, or the card may be bent and snapped into placev beneath the finger, which thereafter prevents its rising, while the placing of the holder flat against the face-plate prevents rearward displacement. The fingers lzf of the frame are curved upon arcs of the circle whose center is at the center of the orifice in the face-plate T. Upon the end of each finger a small portion h is turned back to form a catch or detent. The fingers if, as shown in Figs. 1 and 52, extend only half-way around their circle, while those in Figs. 3, 4, 5, and 6 form a complete circle, or substantially so. The length of these fingers or the angular dimension of their are forms no limitation of my invention. In any case the front plate T has formed in the. flange t certain notches 25, which cooperate with the overturned ends or projections on the fingers 7L3. In Figs. 1 and 2 these notches are shown as double and located diametrically opposite each other, while in Figs.

2 reuse 3, 4, 5, and 6 they are consolidated into one notch, lying upon the lower side of the flange 2," and receiving both projections if.

My holder thus described is placed in position as follows: The mouthpiece T is first removed or partly unscrewed, and the fingers A are laid upon the flange 2," so that the projections It lie within the notch or notches The rnouthpiece is then screwed home, and, as clearly shown in Figs. 1 and 3, 5 and 6, the holder is at once firmly and iminovably clamped in position.

Fig. 2 represents a typical form of my invention, and Fig. 4 a development thereof by lengthening of the fingers. Fig. 5 shows the ultimate extension, wherein the two fingers k together with the portions if of the frame, form a complete ring surrounding the mouthpiece and provided with a projection it, which takes into the notch 25 to retain the holder in position.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An attachment for telephone-transmitters comprising a sight or body portion, an extension therefrom adapted for contact with transmitter parts, said extension having a bent retaining portion, substantially as described.

2. An attachment for telephone-transmitters comprising a sight or body portion ,and an extension therefrom adapted for contact with transmitter parts and having a portion bent out of the plane thereof to form a projection, substantially as described.

3. The combination with a telephone-transmitter having a front plate and a mouthpiece, said front plate being provided with a notch, of an attachment having a sight or body portion, an extension therefrom adapted to be clamped between the transmitter-mouthpiece and front plate and formed with a projection to cooperate with said notch, substantially as described.

4. An attachment for telephone-transmitters comprising a sight or body portion consisting of a light open frame adapted to receive a number or other slip and provided with an extension designed for contact with transmitter parts, said extension having a bent retaining portion, substantially as described.

5. An attachment for telephone-transmitters having a sight or body portion and provided with fingers formed to surround and underlie tli'e transmitter-mouth piece, one of said fingers having a portion bent to form a projection, substantially as described.

6. An attachment for telephone-transmitters having a sight or body portion provided with fingers, said fingers being provided with a projection, substantially as described.

7. An attachment for telephone-transmitters comprising a sight orbody portion, and an extension therefrom adapted to be clamped between transmitter parts, said extension being formed with means to prevent the attachment from turning when said clamping parts are loosened, substantially as described.

8. The combination with a telephone-transmitter having a front plate and amouthpiece, of an attachment for said transmitter comprising a sight or body portion and an extension adapted to be clamped between said mouthpiece and front plate, said extension and front plate being formed to prevent turning of the attachment when said mouthpiece is loosened or partly disengaged, substantially as described.

9. The combination with a telephone-transmitter having a front plate and a mouthpiece, of an attachment for said transmitter comprising a sight or body portion having fingers adapted to be clamped between said mouthpiece and front plate, said front plate having a notch, and one of said fingers having a projection to engage said notch when the mouthpiece is attached to the front plate, substantially as described.

In testimony whereof I aifix my signature in presence of two witnesses.
